Advice wanted: zwave_error: Z-Wave error 202

Configuration Z-Wave
1

I have increased the amount of ZWave devices in my network in the last couple of months. My whole network exists of Fibaro wall plugs, Fibaro dimmers and Switches. The temperature sensors are all Aeotec aërQ Temperature & Humidity Sensors. My controller is a Zooz ZST39 LR. I have total of 64 devices added to my controller.

Now that I have a lot more devices and 1 controller, I noticed that I seem to get more errors. I never had these errors before when the network had between 20 and 30 devices.

They errors look mainly like this:
Error while executing automation automation.bedroom_power_plug_television_turn_off_in_absence: Unable to set value 35-37-0-targetValue: zwave_error: Z-Wave error 202 - Failed to send the command after 1 attempts (ZW0202)

This happens now once or twice a day. For the record, the error occurred when an automation had to turn of a Fibaro Wall plug.
The power plug does respond to my command when I manually turn it on and off in HA. So it is available. No devices are offline. The error happens with other plugs sometimes too.

I have tried rebuilding the routes of my network. But after having done that, I noticed that I have a lot more red lines then I did before.

Would a range extender help to prevent these errors? I was looking at the Aeotec Range Extender 7

Done a lot of re-interviewing devices today. And now most devices have green lines for the routes. But the problem still remains. Had the same kind of error again for turning off a light switch this evening. It’s almost never the same device. It seems to be random.

I could be mistaken but I don’t believe the color of the lines on the Z-wave-JS UI network map has anything to do with the quality of the connection. At least according to the Map Legend shown under options.

Hmm ok.

I am starting to think the error is a software issue. I see more people with different controllers, etc having the same issue with ZWaveJS after some recent updates.

Wondering if I can downgrade to an earlier version.
